1 Claim.

This invention relates to a new and improved window construction.

Windows for buildings and particularly residential buildings are made in many ways, yet none of these windows provides for easy external cleaning and maintenance during the time storm or screen sash are positioned on the outside thereof. There has recently appeared on the market many combination windows which provide for storm or screen sash, but as in the past maintenance of the windows practically impossible without a dismantling of the entire unit. It is therefore an important object of the present invention to provide a window construction enabling ready access for washing and other maintenance at all times regardless of whether or not screen or storm sash are used.

Another important object of this invention is to provide a combined unit consisting of a regular window and/or a storm or screen sash associated therewith.

Another and further important object of this invention is the provision of a combination regular window with storm or screen sash adapted to swing inwardly as a unit for ready access to the separate parts thereof.

Still another object of this invention is to provide a combined regular window with storm or screen sash hinged for inward swinging movement and having therein the regular window hingedly mounted for separate inward swinging movement.

Another and still further important object of this invention is the provision of dual sealing means for inward swinging windows providing for eflicient insulation and a minimum loss of heat through the window frame.

A still further object of this invention is to provide a window construction swingable inwardly as a unit and having a storm sash removably positioned in one portion thereof for easy and quick replacement by a screen sash or vice versa.

Other and further important objects will become apparent from the disclosures in the following specification and accompanying drawings.

In the drawings:

Figure 1 is a front elevationalview of a window sash incorporating the structural principles of my invention.

Figure 2 is a sectional View taken on the line 2-2 of Figure 1.

Figure 3 is a perspective view of the window sash of Figures 1 and 2 showing the window in open position.

Figure 4 shows a front elevational view of a modified form of window construction of this invention,

Figure 5 is still another modified form incorporating the window construction principles of this invention.

As shown in the drawings:

The reference numeral Ii] indicates generally a main frame adapted to be positioned in a substantially rectangular opening in a building wail H. The frame II! corresponds to and is somewhat similar to the frames build in for the presently used building window constructions. The window construction of the present invention may be made with a metal frame or wooden frame as desired. However, it is believed that the new construction is particularly suited for metal frames for the reason that less space is provided for a window unit of comparable strength. An inner auxiliary frame I2 is hingedly mounted at I3 to the fixed main frame I9 which in turn is mounted in the building wall II. The fixed main frame I E] is provided with spaced peripheral offsets or shoulder portions I4 and I5 which extend around the entire periphery of the substantially rectangular frame and are respectively adjacent the inner and outer surface of the wall II. The inner hinged auxiliary frame I2 is similarly provided with spaced peripheral external offset portions I6 and H which mate with the offset shoulder portions I4 and I5 respectively of the outer main frame. Intermediate these spaced mating shoulders It and I6, and I5 and I! sealing members are positioned. These sealing members designated as I8 and I9 may be of rubber, felt, or some composition which effectively seals the passage of cold or warm air. These seals extend around the entire window and maintain a dead air space 28 between the spaced seals I8 and I9 which effectively insulates the window construction between the inner and outer Walls of the building.

A latching or locking member 2I is adapted to hold the hinged frame I2 in locked position and closed with respect to the outer stationary frame member I0. As shown in Figure 1 the latch member 2| is pivoted at 22 on the fixed frame I0 and has its main arm portion swingable into position over the hinged frame I2.

The hinged auxiliary frame member I2 is provided with an internal flange member 23 positioned substantially centrally of the frame I2 and extending entirely around the internal surface thereof. This flange 23 provides spaced peripheral shoulders against which inner and outer window sash may be positioned. A first window sash 24 having a frame 25 is hinged at 26 to the hinged frame or window structure I2. An insulating or sealing member 21 is preferably positioned intermediate the window frame 25 and the internal flange means 23 providing adequate seals for the window. A latch member 28, comparable to the latch member 2| is pivoted at 29 on the auxiliary window structure 12 as shown in Figs. 1, 2, and 3. The arm portion of the latch 28 extends over the window frame 25 holding it in closed position with respect to the hinged window frame 12 as best shown in Figure 2. It is thus obvious that the window may be opened by swinging the window structure l2 about the hinges 13 after preliminarily releasing the latch member 2|, and/or the first window sash 24 may be separately opened about its hinge 26. This latter is accomplished by releasing the latch 28. In either event they are both swung inwardly of the wall I l.

A storm or screen sash is adapted to be positioned against the outer side of the flange 23 thus providing a combination window. This storm sash is designated as numeral 30 and similarly is equipped with a frame 3!. A sealing member 32 is provided between the frame 3! of the storm or screen sash and the flange 23. The sash 30 is adapted for removability within the shoulder defined by the window structure [2 and its flange 23 and is removably held therein by rotating holding members 33 which are pivoted at 34 on the hinged window structure l2. Thus it will be seen that a double seal is provided throughout the entire window construction. In the outer frame members there are the sealing members 18 and 'i 9 and in the inner window portions there are the seals 21 and 32.

In operation when it is desired to wash the windows the inside of the first window is washed after which it is opened by means of the latch 28 and swung about the hinges 26 and the outside of the regular window is washed. This of course brings into position the inside of the storm sash whereupon it may be washed. Subsequently in order to gain access to the outside of the storm sash the auxiliary frame 12 is opened about its hinges l3 by means of rotating the latch 2| and the outer side of the storm sash window is brought into the room whereby the window washer may easily and safely wash the last side of both windows. With the construction just described there is no reason why windows may not be washed from inside to outside even with storm sash during the winter months. Not only is the cleaning of the windows made easy, but the replacing of the storm windows by screen sash or vice-versa is made simple inasmuch as the frame for receiving the storm and screen sash is swung into the inside of the building during mounting and dismounting.

In the device of Figure 4 the same general construction is employed with the exception that the inner main window is not shown in one full section but rather is divided vertically centrally of the frame as shown at 35 thus defining a left and right window 36 and 31 respectively which latch together by means of the member 38. In

the modified device of Figure 5 the inner window is divided into upper and lower portions 39 and 40 which hinge at 4| and 42 and are latched by the latch members 43 and 44 respectively.

It will thus be seen that the window construc= tion of this invention provides for simple and easily operated sash which contribute to cleaning and maintenance of the window panes and screen employed in this device. Further the in-' sulation provided by the sealing means spaced apart from each other effectively provide stoppage of air currents therethrough thus making for a very successful window construction.

I am aware that numerous details of construetion may be varied throughout a wide range without departing from the principles disclosed herein and I therefore do not propose limiting the patent granted hereon otherwise than as necessitated by the appended claim.

What is claimed is:

A Window construction for a substantially rectangular opening in a wall having an inside and an outside, comprising a fixed main frame outlining the periphery of the rectangular wall opening, said fixed main frame having spaced peripheral offsets, the first of said peripheral oifsets being located adjacent the outside of the wall, the second of said peripheral offsets being located adjacent the inside of the wall and spaced from the first of said peripheral offsets, an auxiliary frame hinged to and within said fixed main frame for swinging movement as an entire unit inwardly of the wall, said auxiliary frame having spaced peripheral external offsets corresponding in size and position to and mating with the offsets in said fixed main frame, said auxiliary frame having internal flange means forming spaced inner and outer peripheral shoulders, a first sash hinged on said auxiliary frame to swing inwardly to open and to lie against the inner of said peripheral shoulders when closed, and a second sash removably positioned in said auxiliary frame against the outer of said peripheral shoulders.
